To get the answer we can use proportion
3 red ----------------- 5 yellow
x red ----------------- 20 yellow
Crossmultiply now
3*20=5x            
60=5x        /:5    (divide both sides by 5)
60:5=5x:5

A rectangular table is four times as long as it is wide. If the area is 36 ft2, find the length and the width of the table.
FrozenT [24]

Answer:

The width is 3 ft

The length is  12 ft

Step-by-step explanation:

Let w = width

l = 4w

A = l*w

Replace length with 4w

A = 4w*w

36 = 4 w^2

Divide each side by 4

36/4 = 4w^2/4

9 = w^2

Take the square root of each side

sqrt(9) = sqrt(w)

3 =w

The width is 3 ft

The length is 4*3 = 12 ft

Hich value, when placed in the box, would result in a system of equations with infinitely many solutions?
Jobisdone [24]

The value placed in the box that makes the system of equation with infinitely many solution is 12.

<h3>How to solve an infinitely many solution equation?</h3>

An infinite solution has both sides equal. For example, 6x + 2y - 8 = 12x +4y - 16.  If we simplify the equation we will notice both sides are equal. This means the equation has an infinitely many solution.

Hence,

y = -2x + 4

Therefore,

6x + 3y = 12

divide the equation(ii) by 3

2x + y = 4

y = -2x + 4

Therefore, both equation are equal if the the box is filled with 12. This means for the value placed in the box that makes the system of equation with infinitely many solution is 12.
